Abstract: A heat sink having a coolant flow path formed inside through which a coolant flows includes: a heat transfer plate having a first surface on which a semiconductor device is disposed and a second surface; a junction flow path-forming plate having a third surface and a fourth surface; a first partition wall provided in contact with the second surface and the third surface; and first fins provided in contact with the second surface. The coolant flow path includes a first flow path. A plurality of first divided regions separated by the at least one first partition wall are formed in the first flow path. The plurality of first fins are arranged by being spaced side by side in the first divided regions.

Abstract: An image generation system includes: a flash image generation section which generates a flash image which increases luminance of scan light for detecting an indication position of a pointing device including a photosensor which detects scan light from a display section; a luminance adjustment processing section which displays a luminance adjustment screen for adjusting luminance of the flash image in the display section, and sets luminance adjustment information of the flash image by luminance adjustment using the luminance adjustment screen; and an image generation section which generates an image displayed in the display section. The flash image generation section generates the flash image at a luminance set by the luminance adjustment information.
